  • How to use google maps API with multiple markers on the same map

    - by Maen
    So, i have the following script to use the google maps API, its all fine, but i need to create a map that has more than one Marker (the balloon shaped icon pointing to something) and i need each of those markers to point on a different area of the map (i.e. different coordinates), how can i do it? <script type="text/javascript"> function load() { var map = new GMap2(document.getElementById("map")); var marker = new GMarker(new GLatLng(<%=coordinates%>)); var html="<img src='simplemap_logo.jpg' width='20' height='20'/> " + "<%=maptitle%><br/>" + "<%=text%>"; map.setCenter(new GLatLng(<%=coordinates%>), <%=zoom%>) map.setMapType(G_HYBRID_MAP); map.addOverlay(marker); map.addControl(new GLargeMapControl()); map.addControl(new GScaleControl()); map.addControl(new GMapTypeControl()); marker.openInfoWindowHtml(html); } //]]> </script> One more question, if i pass the Script text as a variable, lets say something like: <script type="text/javascript"> <%=ScriptText%> </script> and my <%=ScriptText% will be a string which i will build and assign its value to a Friend or Public variable called ScriptText, will it still run and work properly? (i am doing this to make my script dynamic and different based on how i build it as a STRING, due to my illiteracy in javascripting ;P)

  • CSS Background image in Redmine template arbitrarily not loading

    - by Pekka
    I`m in the process of building a template for Redmine (a project management system based on Ruby on Rails.) Ruby is running on a virtual server from a Bitnami.org installation package. The OS is Windows. The template essentially consists of a styles.css file. In that file, I have the following line: #header { padding: 0px; padding-top: 48px; background-color: #62DFFF; background-image: url(../images/bkg.jpg) background-position: center bottom; background-repeat: repeat-x; height:150px; } It's a header element with a background image. The problem: This background image arbitrarily appears and disappears when reloading. Say you reload ten times in twenty seconds; the image will appear in two instances, and be missing in the 18 others. I would have put this down to server problems, but the weird thing is that when it's missing, the request for the image doesn't appear in Firebug's net tab at all. Even if it were cached, the request should be there. Raw screenshots of the identical page on two reloads: I am 100% sure the CSS file does not change in between. I have examined both instances with Firebug and the CSS is identical. It happens in both Firefox and Chrome so it must be something basic I'm overlooking. What could be causing a browser not to load a resource at all? I have zero idea about Ruby nor Rails - getting Redmine running and customized is all I have ever had to do with this platform - so I don't really know where to look. Apache's, Mongrel's and Redmine's error logs look fine, though.

  • Modify XML existing content in C#

    - by Nano HE
    Purpose: I plan to Create a XML file with XmlTextWriter and Modify/Update some Existing Content with XmlNode SelectSingleNode(), node.ChildNode[?].InnerText = someting, etc. After I created the XML file with XmlTextWriter as below. XmlTextWriter textWriter = new XmlTextWriter("D:\\learning\\cs\\myTest.xml", System.Text.Encoding.UTF8); I practiced the code below. But failed to save my XML file. XmlDocument doc = new XmlDocument(); doc.Load("D:\\learning\\cs\\myTest.xml"); XmlNode root = doc.DocumentElement; XmlNode myNode; myNode= root.SelectSingleNode("descendant::books"); .... textWriter.Close(); doc.Save("D:\\learning\\cs\\myTest.xml"); I found it is not good to produce like my way. Is there any suggestion about it? I am not clear about the concepts and usage of both XmlTextWriter and XmlNode in the same project. Thank you for reading and replies.

  • Total row count for pagination using JPA Criteria API

    - by ThinkFloyd
    I am implementing "Advanced Search" kind of functionality for an Entity in my system such that user can search that entity using multiple conditions(eq,ne,gt,lt,like etc) on attributes of this entity. I am using JPA's Criteria API to dynamically generate the Criteria query and then using setFirstResult() & setMaxResults() to support pagination. All was fine till this point but now I want to show total number of results on results grid but I did not see a straight forward way to get total count of Criteria query. This is how my code looks like: CriteriaBuilder builder = em.getCriteriaBuilder(); CriteriaQuery<Brand> cQuery = builder.createQuery(Brand.class); Root<Brand> from = cQuery.from(Brand.class); CriteriaQuery<Brand> select = cQuery.select(from); . . //Created many predicates and added to **Predicate[] pArray** . . select.where(pArray); // Added orderBy clause TypedQuery typedQuery = em.createQuery(select); typedQuery.setFirstResult(startIndex); typedQuery.setMaxResults(pageSize); List resultList = typedQuery.getResultList(); My result set could be big so I don't want to load my entities for count query, so tell me efficient way to get total count like rowCount() method on Criteria (I think its there in Hibernate's Criteria).

  • JSF: Avoid nested update calls

    - by dhroove
    I don't know if I am on right track or not still asking this question. I my JSF project I have this tree structure: <p:tree id="resourcesTree" value="#{someBean.root}" var="node" selectionMode="single" styleClass="no-border" selection="#{someBean.selectedNode}" dynamic="true"> <p:ajax listener="#{someBean.onNodeSelect}" update=":centerPanel :tableForm :tabForm" event="select" onstart="statusDialog.show();" oncomplete="statusDialog.hide();" /> <p:treeNode id="resourcesTreeNode" > <h:outputText value="#{node}" id="lblNode" /> </p:treeNode> </p:tree> I have to update this tree after I added something or delete something.. But whenever I update this still its nested update also call I mean to say it also call to update these components ":centerPanel :tableForm :tabForm"... This give me error that :tableForm not found in view because this forms load in my central panel and this tree is in my right panel.. So when I am doing some operation on tree is it not always that :tableForm is in my central panel.. (I mean design is something like this only) So now my question is that can I put some condition or there is any way so that I can specify when to update nested components also and when not.... In nut shell is there any way to update only :resoucesTree is such a way that nested updates are not called so that I can avoid error... Thanks in advance.

  • Issue while saving image using savefiledialog

    - by user1097772
    I'm using savefiledialog to save an image. Canvas is picturebox and the loaded image is bitmap. When I try to save it the file is created but somehow corrupted. Cause when I try againt load the image or show in different viewer it doesn't work - I mean the saved file is corrupted. There is an method for saving image. private void saveFileDialog1_FileOk(object sender, CancelEventArgs e) { System.IO.FileStream fs = (System.IO.FileStream)saveFileDialog1.OpenFile(); try { switch (saveFileDialog1.FilterIndex) { case 1: canvas.Image.Save(saveFileDialog1.FileName, System.Drawing.Imaging.ImageFormat.Bmp); break; case 2: canvas.Image.Save(saveFileDialog1.FileName, System.Drawing.Imaging.ImageFormat.Jpeg); break; case 3: canvas.Image.Save(saveFileDialog1.FileName, System.Drawing.Imaging.ImageFormat.Png); break; case 4: canvas.Image.Save(saveFileDialog1.FileName, System.Drawing.Imaging.ImageFormat.Tiff); break; } } catch (Exception ex) { System.Console.WriteLine("Exception " + ex); } I should also mention the property Filter. saveFileDialog1.Filter has value: bmp (*.bmp)|*.bmp|jpeg (*.jpeg)|*.jpeg|png (*.png)|*.png|tiff (*.tiff)|*.tiff

  • Facebook Like Meta Tags not showing Images

    - by Hooman Ahmadi
    I have implemented the Facebook Like button on all our pages and it works properly by posting to Facebook with the correct meta tags. However, the images do not show in Facebook. The image meta tags show up properly when I use the Facebook Linter, but they don't show on someone's facebook page where the Like is posted on their wall. Also, is there any way to have the info recache more often? The tags take forever to update. Our site is built with CakePHP. Below are snippets of my code, thanks: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml"> <head> <script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script> <script type="text/javascript" src="http://use.typekit.com/wlx8xgm.js"></script> <script type="text/javascript">try{Typekit.load();}catch(e){}</script> <?php if(!isset($meta_title)) { $meta_title = $title_for_layout; } if(!isset($meta_location)) { $meta_location = null; } if(!isset($meta_image)) { $meta_image = null; } if(!isset($meta_type)) { $meta_type = null; } ?> <meta property="og:title" content="<?= $meta_title ?>"/> <meta property="og:type" content="<?= $meta_type ?>"/> <meta property="og:url" content="<?= $meta_location ?>"/> <meta property="og:image" content="<?= $meta_image ?>"/> <meta property="fb:admins" content="1004432800"/> ... echo '<br><br><fb:like href="' . $fbook_url .

  • Concurrent WCF calls via shared channel

    - by Kent Boogaart
    I have a web tier that forwards calls onto an application tier. The web tier uses a shared, cached channel to do so. The application tier services in question are stateless and have concurrency enabled. But they are not being called concurrently. If I alter the web tier to create a new channel on every call, then I do get concurrent calls onto the application tier. But I wanted to avoid that cost since it is functionally unnecessary for my scenario. I have no session state, and nor do I need to re-authenticate the caller each time. I understand that the creation of the channel factory is far more expensive than than the creation of the channels, but it is still a cost I'd like to avoid if possible. I found this article on MSDN that states: While channels and clients created by the channels are thread-safe, they might not support writing more than one message to the wire concurrently. If you are sending large messages, particularly if streaming, the send operation might block waiting for another send to complete. Firstly, I'm not sending large messages (just a lot of small ones since I'm doing load testing) but am still seeing the blocking behavior. Secondly, this is rather open-ended and unhelpful documentation. It says they "might not" support writing more than one message but doesn't explain the scenarios under which they would support concurrent messages. Can anyone shed some light on this?

  • Why does Tex/Latex not speed up in subsequent runs?

    - by Debilski
    I really wonder, why even recent systems of Tex/Latex do not use any caching to speed up later runs. Every time that I fix a single comma*, calling Latex costs me about the same amount of time, because it needs to load and convert every single picture file. (* I know that even changing a tiny comma could affect the whole structure but of course, a well-written cache format could see the impact of that. Also, there might be situations where 100% correctness is not needed as long as it’s fast.) Is there something in the language of Tex which makes this complicated or impossible to accomplish or is it just that in the original implementation of Tex, there was no need for this (because it would have been slow anyway on those large computers)? But then on the other hand, why doesn’t this annoy other people so much that they’ve started a fork which has some sort of caching (or transparent conversion of Tex files to a format which is faster to parse)? Is there anything I can do to speed up subsequent runs of Latex? Except from putting all the stuff into chapterXX.tex files and then commenting them out?

  • GWT: Populating a page from datastore using RPC is too slow

    - by Ilya Boyandin
    Is there a way to speed up the population of a page with GWT's UI elements which are generated from data loaded from the datastore? Can I avoid making the unnecessary RPC call when the page is loaded? More details about the problem I am experiencing: There is a page on which I generate a table with names and buttons for a list of entities loaded from the datastore. There is an EntryPoint for the page and in its onModuleLoad() I do something like this: final FlexTable table = new FlexTable(); rpcAsyncService.getAllCandidates(new AsyncCallback<List<Candidate>>() { public void onSuccess(List<Candidate> candidates) { int row = 0; for (Candidate person : candidates) { table.setText(row, 0, person.getName()); table.setWidget(row, 1, new ToggleButton("Yes")); table.setWidget(row, 2, new ToggleButton("No")); row++; } } ... }); This works, but takes more than 30 seconds to load the page with buttons for 300 candidates. This is unacceptable. The app is running on Google App Engine and using the app engine's datastore.

  • Zend framework controller action helper

  • Converting an AnsiString to a Unicode String

    - by jrodenhi
    I'm converting a D2006 program to D2010. I have a value stored in a single byte per character string in my database and I need to load it into a control that has a LoadFromStream, so my plan was to write the string to a stream and use that with LoadFromStream. But it did not work. In studying the problem, I see an issue that tells me that I don't really understand how conversion from AnsiString to Unicode string works. Here is some code I am puzzling over: oStringStream := TStringStream.Create(sBuffer); sUnicodeStream := oPayGrid.sStream; //explicit conversion to unicode string iSize1 := StringElementSize(oPaygrid.sStream); iSize2 := StringElementSize(sUnicodeStream); oStringStream.WriteString(sUnicodeStream); When I get to the last line, iSize1 does equal 1 and iSize2 does equal 2, so that part is what I understood from my reading. But, on the last line, after I write the string to the stream, and look at the Bytes Property of the string, it shows this (the string starts as '16,159'): (49 {$31}, 54 {$36}, 44 {$2C}, 49 {$31}, 53 {$35}, 57 {$39} ... I was expecting that it might look something like (49 {$31}, 00 {$00}, 54 {$36}, 00 {$00}, 44 {$2C}, 00 {$00}, 49 {$31}, 00 {$00}, 53 {$35}, 00 {$00}, 57 {$39}, 00 {$00} ... I'm not getting the right results out of the LoadFromStream because it is reading from the stream two bytes at a time, but the data it is receiving is not arranged that way. What is it that I should do to give the LoadFromStream a well formed stream of data based on a unicode string? Thank you for your help.

  • How to append a row to a TableViewSection in Titanium?

    - by Mike Trpcic
    I'm developing an iPhone application in Titanium, and need to append a row to a particular TableViewSection. I can't do this on page load, as it's done dynamically by the user throughout the lifecycle of the application. The documentation says that the TableViewSection has an add method which takes two arguments, but I can't make it work. Here's my existing code: for(var i = 0; i <= product_count; i++){ productsTableViewSection.add( Ti.UI.createTableViewRow({ title:'Testing...' }) ); } That is just passing one argument in, and that causes Titanium to die with an uncaught exception: 2010-04-26 16:57:18.056 MyApplication[72765:207] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 2. The number of rows contained in an existing section after the update (2) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (0 inserted, 0 deleted).' 2010-04-26 16:57:18.056 MyApplication[72765:207] Stack: ( The exception looks like it did add the row, but it's not allowed to for some reason. Since the documentation says that TableViewSection takes in "view" and "row", I tried the following: for(var i = 0; i <= product_count; i++){ productsTableViewSection.add( Ti.UI.createView({}), Ti.UI.createTableViewRow({ title:'Testing...' }) ); } The above code doesn't throw the exception, but it gives a [WARN]: [WARN] Invalid type passed to function. expected: TiUIViewProxy, was: TiUITableViewRowProxy in -[TiUITableViewSectionProxy add:] (TiUITableViewSectionProxy.m:62) TableViewSections don't seem to support any methods like appendRow, or insertRow, so I don't know where else to go with this. I've looked through the KitchenSink app, but there are no examples that I could find of adding a row to a TableViewSection. Any help is appreciated.

  • Starting with NHibernate

    - by George
    I'm having major difficulties to start off with NHiberante. Main problems: Where my hbm.xml files should reside? I create a Mappings folder but I received an error "Could not find xxx.hbm.xml file." I tried to load the specific class through the dialect cf.AddClass(typeof(xxx)); but it still gives me the same error (the files are marked as embebed resources. Also I'm having major problems in connection to it. I stopped trying to use the cfg xml file and tried a more direct approach with a library I have here. Configuration cfg = new Configuration(); cfg.AddClass(typeof(Tag)); ISessionFactory sessions = cfg.BuildSessionFactory(); AgnosticConnectionHandler agch = new AgnosticConnectionHandler("xxx","xxx","geo_biblio","localhost", 5432,DatabaseInstance.PostgreSQL); ISession sessao = sessions.OpenSession(agch.GetConnection); ITransaction tx = sessao.BeginTransaction(); Tag tag1 = new Tag(); tag1.NomeTag = "Teste Tag NHibernate!!!"; sessao.Save(tag1); tx.Commit(); sessao.Close(); Any tips for me? I'm getting the exception in line 2 of this code, and still not sure what to do. Any help is appreciated. Thanks

  • _dl_runtime_resolve -- When do the shared objects get loaded in to memory?

    - by windfinder
    We have a message processing system with high performance demands. Recently we have noticed that the first message takes many times longer then subsequent messages. A bunch of transformation and message augmentation happens as this goes through our system, much of it done by way of external lib. I just profiled this issue (using callgrind), comparing a "run" of just one message with a "run" of many messages (providing a baseline of comparison). The main difference I see is the function "do_lookup_x" taking up a huge amount of time. Looking at the various calls to this function, they all seem to be called by the common function: _dl_runtime_resolve. Not sure what this function does, but to me this looks like the first time the various shared libraries are being used, and are then being loaded in to memory by the ld. Is this a correct assumption? That the binary will not load the shared libraries in to memory until they are being prepped for use, therefore we will see a massive slowdown on the first message, but on none of the subsequent? How do we go about avoiding this? Note: We operate on the microsecond scale.

  • PHP Object References in Frameworks

    - by bigstylee
    Before I dive into the disscusion part a quick question; Is there a method to determine if a variable is a reference to another variable/object? For example $foo = 'Hello World'; $bar = &$foo; echo (is_reference($bar) ? 'Is reference' : 'Is orginal'; I have been using PHP5 for a few years now (personal use only) and I would say I am moderately reversed on the topic of Object Orientated implementation. However the concept of Model View Controller Framework is fairly new to me. I have looked a number of tutorials and looked at some of the open source frameworks (mainly CodeIgnitor) to get a better understanding how everything fits together. I am starting to appreciate the real benefits of using this type of structure. I am used to implementing object referencing in the following technique. class Foo{ public $var = 'Hello World!'; } class Bar{ public function __construct(){ global $Foo; echo $Foo->var; } } $Foo = new Foo; $Bar = new Bar; I was surprised to see that CodeIgnitor and Yii pass referencs of objects and can be accessed via the following method: $this->load->view('argument') The immediate advantage I can see is a lot less code and more user friendly. But I do wonder if it is more efficient as these frameworks are presumably optimised? Or simply to make the code more user friendly? This was an interesting article Do not use PHP references.

  • Changing a url depending on what link chosen (HTML) no asp.

    - by Ozaki
    TLDR I need to change a javascript variable on the same page after clicking a link (can be from a different page) so that the getjson request pulls different data without having to duplicate on html pages. I am using some getJSON requests with Jquery, to make calls to populate my pages. I want to be able to (in plain HTML / javascript) when the user clicks say "link 1" or "link 2" to open the same page (say page.html) but change the get request url to "link 1" or "link 2". Page.html var url = ??; $.getJSON(url, function(data){} link 1 var url = host/link1 <a href="page.html">link1</a> link2 var url = host/link2 <a href="page.html">link2</a> So I call the same page but am able to populate it with different content. Purposely staying away from asp. Was thinking maybe of inserting the content into a div after page load so the url can be set or something along those lines. Any ideas how I might go about this?

  • Javascript: Onload if checkbox is checked, change li class

    I have this code on javascript side: function changeSelectionStyle(id) { if(document.getElementById(id).className != 'yes'){ document.getElementById(id).className = 'yes'; } else{document.getElementById(id).className = '';} } And this on html: <ul> <li id="selectedAuthorities-4_1li" class=""> <input type="checkbox" id="selectedAuthorities-4_1" name="selectedAuthorities" value="ROLE_ADD_COMMENT_TO_CV" checked="checked" onload="changeSelectionStyle(this.id + 'li');" onclick="changeSelectionStyle(this.id + 'li'); checkFatherSelection(this.id);"> <a href="#" onclick="document.getElementById('selectedAuthorities-4_1').click(); return false;"> Agregar comentario <samp><b></b>Permite agregar comentario en el detalle.</samp> </a> </li> Well what I cant get work is when the checkbox is selected, on load, the JS should check it, and assign class="yes" to the li, here: <li id="selectedAuthorities-4_1li" class=""> What should I add to my original JS function to make that possible. Note that li ids are not static, they are dynamic, the html li id is generated.

  • Need to calculate rotation-vector from Sensor.TYPE_ORIENTATION data

    - by Sponge
    I need to calculate a rotation vector out of the data i get from Sensor.TYPE_ORIENTATION. The sensor data is defined like this: the values have to be recalculated to become a correct 3d position: values[0]: Azimuth, angle between the magnetic north direction and the Y axis, around the Z axis (0 to 359). 0=North, 90=East, 180=South, 270=West values[1]: Pitch, rotation around X axis (-180 to 180), with positive values when the z-axis moves toward the y-axis. values[2]: Roll, rotation around Y axis (-90 to 90), with positive values when the x-axis moves away from the z-axis I need all three values like the Z axis value (from 0 to 360 degree). I tried a lot but cant figure out how to do this :/ i also tried to use Sensor.TYPE_ACCELEROMETER and Sensor.TYPE_MAGNETIC_FIELD to calculate this 3d vector on my own. here is the code: final float[] inR = new float[16]; // load inR matrix from current sensor data: SensorManager.getRotationMatrix(inR, null, gravityValues, geomagneticValues); float[] orientation = new float[3]; SensorManager.getOrientation(inR, orientation); mapMagAndAcclDataToVector(orientation); //here i do some *360 stuff orientetionChanged(orientation); //then the correct values are passed (in theorie) But this didn't work and i think it is much to complicated. So i bet there is a simple solution how to recalc the values of ensor.TYPE_ORIENTATION to make them a 3d rotation vector, but i just dont know how to do it. If you know the answer please tell me.

  • Cast object to interface when created via reflection

    - by Al
    I'm trying some stuff out in Android and I'm stuck at when trying to cast a class in another .apk to my interface. I have the interface and various classes in other .apks that implement that interface. I find the other classes using PackageManager's query methods and use Application#createPackageContext() to get the classloader for that context. I then load the class, create a new instance and try to cast it to my interface, which I know it definitely implements. When I try to cast, it throws a class cast exception. I tried various things like loading the interface first, using Class#asSubclass, etc, none of which work. Class#getInterfaces() shows the interface is implemented. My code is below: PackageManager pm = getPackageManager(); List<ResolveInfo> lr = pm.queryIntentServices(new Intent("com.example.some.action"), 0); ArrayList<MyInterface> list = new ArrayList<MyInterface>(); for (ResolveInfo r : lr) { try { Context c = getApplication().createPackageContext(r.serviceInfo.packageName, Context.CONTEXT_IGNORE_SECURITY | Context.CONTEXT_INCLUDE_CODE); ClassLoader cl = c.getClassLoader(); String className = r.serviceInfo.name; if (className != null) { try { Class<?> cls = cl.loadClass(className); Object o = cls.newInstance(); if (o instanceof MyInterface) { //fails list.add((MyInterface) o); } } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } // some exceptions removed for readability } } catch (NameNotFoundException e1) { e1.printStackTrace(); }

    At the moment my repository has 2 constructors. When i call these from my mvc website i am alway calling first constructor and thus opening a new session. Should i been passing in the session. How should i be doing this. public CompanyRepository() { _session = NHibernateHelper.OpenSession(); } public CompanyRepository(ISession session) { _session = session; } public class NHibernateHelper { private static ISessionFactory _sessionFactory; private static ISessionFactory SessionFactory { get { if (_sessionFactory == null) { var configuration = new Configuration(); configuration.Configure(); configuration.AddAssembly(typeof(UserProfile).Assembly); configuration.SetProperty(NHibernate.Cfg.Environment.ConnectionStringName, System.Environment.MachineName); _sessionFactory = configuration.BuildSessionFactory(); } return _sessionFactory; } } public static ISession OpenSession() { return SessionFactory.OpenSession(); } } I'm using the Ninject IOC container ( very new to me ). I have the following container. How would i bind the ISession to the CompanyRepository. private class EStoreDependencies : NinjectModule { public override void Load() { Bind<ICompanyRepository>().To<CompanyRepository>(); Bind<IUserProfileRepository>().To<UserProfileRepository>(); Bind<IAddressRepository>().To<AddressRepository>(); Bind<IRolesService>().To<AspNetRoleProviderWrapper>(); Bind<IUserService>().To<AspNetMembershipProviderWrapper>(); Bind<ICurrentUserSerivce>().To<DefaultCurrentUserSerivce>(); Bind<IPasswordService>().To<AspNetMembershipProviderWrapper>(); Bind<IStatusResponseRepository>().To<StatusResponseRepository>(); Bind<ICategoryRepository>().To<CategoryRepository>(); Bind<IProductRepository>().To<ProductRepository>(); } }

  • I am not able to update form data to MySQL using PHP and jQuery

    - by Jimson Jose
    My problem is that I am unable to update the values entered in the form. I have attached all the files. I'm using MYSQL database to fetch data. What happens is that I'm able to add and delete records from form using jQuery and PHP scripts to MYSQL database, but I am not able to update data which was retrieved from the database. The file structure is as follows: index.php is a file with jQuery functions where it displays form for adding new data to MYSQL using save.php file and list of all records are view without refreshing page (calling load-list.php to view all records from index.php works fine, and save.php to save data from form) - Delete is an function called from index.php to delete record from MySQL database (function calling delete.php works fine) - Update is an function called from index.php to update data using update-form.php by retriving specific record from MySQL table, (works fine) Problem lies in updating data from update-form.php to update.php (in which update query is written for MySQL) I have tried in many ways - at last I had figured out that data is not being transferred from update-form.php to update.php; there is a small problem in jQuery AJAX function where it is not transferring data to update.php page. Something is missing in calling update.php page it is not entering into that page. I am new bee in programming. I had collected this script from many forums and made this one. So I was limited in solving this problem. I came to know that this is good platform for me and many where we get a help to create new things. Please find the link below to download all files which is of 35kb (virus free assurance): download mysmallform files in ZIPped format, including mysql query

  • How to manage data access / preloading efficiently using web services in C# ?

    - by Amadeus45
    Hello all, Ok, this is very "generic" question. We currently have a SQL Server database for which we need to develop an application in ASP.NET with will contain all the business logic in C# Web Services. The thing is that, architecturally speaking, I'm not sure how to design the web service and the data management. There are many things to consider : We need have very rapid access to data. Right now, we have over a million "sales" and "purchases" record from which we need to often calculate and load the current stock for a given day according to a serie of parameter. I'm not sure how we should preload the data and keep the data in the Web Service. Doing a stock calculation within a SQL query will be very lengthy. They currently have a stock calculation application that preloads all sales and purchases for the day and afterwards calculate the stock on the code-side. We want to develop powerful reporting tools. We want to implement a "pivot table" but not sure how to implement it and have good performances. For the reasons above, I'm not sure how to design the data model. Anybody can give me any guidelines on how to start, or from their personnal experiences (what have you done in the past ?) I'm not sure if it's possible to make a bounty even though the question is new (I'd put 300 rep on it, since I really need something). If you know how, let me know. Thanks

  • Does Android AsyncTaskQueue or similar exist?

    - by Ben L.
    I read somewhere (and have observed) that starting threads is slow. I always assumed that AsyncTask created and reused a single thread because it required being started inside the UI thread. The following (anonymized) code is called from a ListAdapter's getView method to load images asynchronously. It works well until the user moves the list quickly, and then it becomes "janky". final File imageFile = new File(getCacheDir().getPath() + "/img/" + p.image); image.setVisibility(View.GONE); view.findViewById(R.id.imageLoading).setVisibility(View.VISIBLE); (new AsyncTask<Void, Void, Bitmap>() { @Override protected Bitmap doInBackground(Void... params) { try { Bitmap image; if (!imageFile.exists() || imageFile.length() == 0) { image = BitmapFactory.decodeStream(new URL( "http://example.com/images/" + p.image).openStream()); image.compress(Bitmap.CompressFormat.JPEG, 85, new FileOutputStream(imageFile)); image.recycle(); } image = BitmapFactory.decodeFile(imageFile.getPath(), bitmapOptions); return image; } catch (MalformedURLException ex) { // TODO Auto-generated catch block ex.printStackTrace(); return null; } catch (IOException ex) { // TODO Auto-generated catch block ex.printStackTrace(); return null; } } @Override protected void onPostExecute(Bitmap image) { if (view.getTag() != p) // The view was recycled. return; view.findViewById(R.id.imageLoading).setVisibility( View.GONE); view.findViewById(R.id.image) .setVisibility(View.VISIBLE); ((ImageView) view.findViewById(R.id.image)) .setImageBitmap(image); } }).execute(); I'm thinking that a queue-based method would work better, but I'm wondering if there is one or if I should attempt to create my own implementation.
